Song, Bingrui published the artcilePalladium/Copper-Catalyzed Di-α-arylation of Acetic Acid Esters, Name: Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I), the publication is Advanced Synthesis & Catalysis (2011), 353(10), 1688-1694, database is CAplus.
A bimetallic palladium/copper catalyst system was found to effectively promote the diarylation of alkyl acetates with aryl halides under unprecedentedly mild conditions. The phenanthroline-copper-phosphine catalyst stabilizes the enolate intermediate to the extent that the deprotonation of esters can be achieved even with the mild base potassium phosphate. The palladium tri-tert-butylphosphine co-catalyst mediates the coupling of the resulting copper enolate with a wide variety of aryl halides with selective formation of the corresponding diarylacetic acid esters.
